Should I check the MOT history before buying a 1999 Rover 623?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

Moderate sample. 439 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 1999 Rover 623 has a first-time MOT pass rate of 70.6%, which is nearly 10 percentage points below the UK average of 80%—a meaningful gap that reflects real reliability concerns. More worryingly, nearly one in four of these vehicles (22.3%) have recorded a dangerous defect at some point, which is well above acceptable levels and should give any prospective buyer pause.

At around 85,000 miles on average, these cars show typical mileage for their age, but they're failing heavily once tested: owners face an average of 3.38 failures and 11.3 advisories per MOT. Before committing to one, get a full pre-purchase inspection focused on brake systems, suspension, and electrical components—the high dangerous defect rate suggests these are the weak points—and factor in higher-than-average repair bills going forward.

The 1999 Rover 623 has a below-average first-time pass rate (70.6% vs ~80% UK average) — check the specific vehicle's full MOT history carefully before buying.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context

⚠️ Below average. More vehicles in this cohort fail their first MOT than typical. Scrutinise this vehicle's history — look for recurring issues, not just the latest result.

🔧 Expect consumable spend. An average of 11.3 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 439 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
